Robin Pre-Training for the Deep Ritz Method
Luca Courte, Marius Zeinhofer
We compare different training strategies for the Deep Ritz Method for elliptic equations with Dirichlet boundary conditions and highlight the problems arising from the boundary val…
Viscosity Solutions for Doubly-Nonlinear Evolution Equations
Luca Courte, Patrick Dondl
We extend the theory of viscosity solutions to treat scalar-valued doubly-nonlinear evolution equations. Such equations arise naturally in many mechanical models including a dry fr…
Pinning of Interfaces by Localized Dry Friction
Luca Courte, Patrick Dondl, Ulisse Stefanelli
We consider a model for the evolution of an interface in a heterogeneous environment governed by a parabolic equation. The heterogeneity is introduced as obstacles exerting a local…
Bounds on Precipitate Hardening of Line and Surface Defects in Solids
Luca Courte, Kaushik Bhattacharya, Patrick Dondl
The yield behavior of crystalline solids is determined by the motion of defects like dislocations, twin boundaries and coherent phase boundaries. These solids are hardened by intro…
